Tug of war
Two teams, two question levels and one friendly contest. Every correct answer earns a step.
A friendly pull. A room full of thinkers.
Play on one screen. Two teams answer independently; each correct answer earns one step. Rotate the player after each question so everyone can join in.
Choose a different question level for each team when useful. There is no timer or penalty for a mistake. No learner accounts or names needed.
